You never treat with medications unless you know what the fish has. The only thing my fish ever get is a PraziPro to make sure they have no worms and it's very mild for them and only takes one treatment.......like once a year.

I would do a water change to get the medication back out of there, lower the temps of 82-84 and maybe not do so many water changes. Baby Discus need water changes a lot but not so much as they get a bit older. Sounds that he/she is guarding that spot. Not sure what the jerking is but my angels do that when they are bickering with others. I hope that's all it is.

Right away - 100% water change (nitrates and phosphates can really harm discus at levels that most fish are fine with; phosphates need to be as close to zero as possible. Nitrates under 5 ppm and lower if possble.)

Then raise the temp to at least 90 F. Add 1 tablespoon of aquarium salt per gal of water. Treat for one to two weeks. This does not in any way stress discus but wil often cure 90% of what ails them. YOU MUST remove any other fish - they can not tolerate such a treatment. By the way, I got this treatment from a breeder that deals with Hans (don't know if they use.)

I've used it a few times with fantastic results. Some plants can handle this treatment once. Since you have a discus tank, and keep them at 84 - 86 F, you have tough plants and they might handle the treatment. Still, I'll take discus health over plants - your call.

A 55 gal is rather small for four large discus - that will stress them badly. They need room to get away from each other at times. That could be the issue. If you can't get a larger tank, consider some large wood to allow them to hide.

I do not trust using any live worms - you are asking for major issues with these. Use sterilized frozen worms and for live, brine shrimp. Others don't always agree but worms, even the best carry a lot of bacteria and in a closed system like a tank, and fish that can get stressed, I feel, leds to trouble. Your call but I often had issues with live worms and since giving them up, have never had a single sick discus in five years. maybe luck but I don't trust live food (except salt based brine shrimp ... .)

Knowledge is fun(damental)

A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

You need to start your own thread for an answer - also, be a bit more clear on what you are asking.
